Description

Technical Field

[0001] This utility model belongs to the field of artificial insect breeding technology, specifically relating to a drawer-type device that integrates rice moth rearing and egg laying. Background Technology

[0002] The rice moth (*Corcyra cephalonica*) is a significant storage pest and an indispensable intermediate or alternative host in the large-scale production of various natural enemy insects, especially egg parasitic wasps such as Trichogramma and Ephraxonema. In the field of biological control, the stable, efficient, and low-cost production of large quantities of healthy, high-quality rice moth eggs is crucial.

[0003] Currently, large-scale rice moth farming generally adopts a separate system of "rearing box + egg-laying cage". This traditional model has the following technical pain points: In the larval rearing stage, newly hatched larvae are placed in a rearing container containing a specific feed (such as a mixture of wheat bran, corn flour, yeast powder, etc.); the larvae feed and grow in the feed; after the adults emerge, they need to be manually transferred to a special egg-laying cage. The transfer process causes mechanical damage to 15-20% of the adults, and 3-4 transfer operations are required every day. The labor cost accounts for 38% of the total cost; during the transfer and operation of the egg-laying device, there is a risk of larvae or adults escaping, which not only causes losses, but may also pollute the environment or affect other batches.

[0004] Therefore, it is necessary to develop a new type of rice moth rearing device to simplify key steps such as larval rearing, adult emergence, and egg laying. Utility Model Content

[0005] This invention aims to solve the problem of mechanical damage to adult rice moths caused by the need for manual transfer during the transition between different stages of rice moth breeding, including larval growth, adult emergence, and egg laying.

[0006] This utility model provides the following technical solution: a box-type device integrating rice moth breeding and egg laying, including a cabinet with three drawers inside, the top drawer being an adult moth capture drawer, the middle drawer being a larval breeding drawer, and the bottom drawer being an adult moth egg laying drawer.

[0007] The larval rearing drawer has a bottom and an open top; the adult insect catching drawer has a mesh top and a removable mesh bottom; when the mesh in the adult insect catching drawer is pulled out, the adult insect catching drawer and the larval rearing drawer are interconnected; when the mesh is inserted into the adult insect catching drawer, it can intercept adult rice moths between the mesh and the mesh; when the adult insect catching drawer is moved to the bottom, it takes over as the adult insect egg-laying drawer.

[0008] Below the adult insect egg-laying drawer is an egg collection unit that can collect the eggs that fall from the mesh plate.

[0009] Furthermore, the egg collection unit includes an egg collection trough and a collection bottle. The egg collection trough is a conical funnel structure that is larger at the top and smaller at the bottom. The egg collection trough is fully covered within the mesh area. The gaps between the top inlets of the egg collection trough are sealed by a flat plate. The gaps between the top inlets of the egg collection trough and the side wall of the cabinet are sealed by a flat plate. The collection bottle is connected to the bottom outlet of the egg collection trough.

[0010] Furthermore, the mouth of the collection bottle is inserted into the bottom outlet of the egg collection trough.

[0011] Furthermore, ribs supporting the drawers are provided on both sides of the cabinet.

[0012] Furthermore, an observation window is provided on the top panel of the cabinet.

[0013] Furthermore, slots are provided on both sides of the adult insect-catching drawer, and the mesh plate is inserted into the slots on both sides of the drawer.

[0014] Furthermore, the adult insect trap drawer has a baffle with a torsion spring hinged to the inside of the mesh plate's insertion interface. When the mesh plate is pulled out, the torsion spring pushes the baffle to close the insertion interface, and when the mesh plate is inserted, it pushes the baffle to flip up.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] This invention provides a drawer-type device that integrates rice moth rearing and egg-laying, completely eliminating the manual transfer of adult moths and significantly reducing damage and labor costs. In traditional methods, after adult moths emerge, they need to be manually transferred from the rearing container to the egg-laying cage, which is frequent and easily causes mechanical damage to 15-20% of the adults. This device, through its structural design of "larval rearing drawer on top and adult moth capturing drawer on the bottom," utilizes the adults' tendency to fly upwards towards light, causing them to automatically fly from the rearing drawer into the upper adult capturing drawer (at the mesh area) after emergence. No manual intervention is required for transfer.

[0017] To capture adult insects, simply insert the mesh after observing a sufficient number, then pull out the entire adult insect capture drawer and replace it with a new empty drawer. The drawer containing the adults is then moved to the bottom to become the egg-laying drawer. The operation is extremely simple. Compared to traditional methods, this significantly reduces the number of steps and time required, and improves the efficiency of large-scale production.

[0018] The three core functions of larval rearing, adult capture, and adult egg laying are integrated into different drawer layers of a single cabinet, resulting in a compact structure that saves space. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0028] like Figures 1-3 As shown: A drawer-type device integrating rice moth rearing and egg-laying, including a cabinet 1, with three drawers arranged inside the cabinet 1: the top drawer is for capturing adult moths 2, the middle drawer is for raising larvae 3, and the bottom drawer is for laying eggs. The larvae raising drawer 3 has a bottom and an open top. The top of the adult moth capturing drawer 2 is a mesh 5, and the bottom is a removable mesh panel 6. When the mesh panel 6 in the adult moth capturing drawer 2 is pulled out, the adult moth capturing drawer 2 and the larvae raising drawer 3 are interconnected. When the mesh panel 6 is inserted into the adult moth capturing drawer 2, it can intercept adult rice moths between the mesh 5 and the mesh panel 6. When the adult moth capturing drawer 2 is moved to the bottom, it is replaced by the adult moth laying drawer 4. An egg collection unit is set below the adult moth laying drawer 4, which can collect the eggs that fall from the mesh panel 6.

[0029] The egg collection unit includes an egg collection trough 7 and a collection bottle 8. The egg collection trough 7 is a cone-shaped funnel structure that is wider at the top and narrower at the bottom. The cone-shaped structure guides the eggs to slide smoothly into the collection bottle 8 at the bottom. The egg collection trough 7 is fully covered within the area of ​​the mesh plate 6. The gaps between the top entrances of the egg collection trough 7 are sealed by a plate. The gaps between the top entrances of the egg collection trough 7 and the side wall of the cabinet 1 are also sealed by a plate. After the adult egg-laying drawer 4 is pulled out, the eggs that fall onto the plate can be manually pushed into the egg collection trough 7 to ensure that all eggs that fall through the mesh of the mesh plate 6 enter the egg collection trough 7 without any dead corners or leaks. The collection bottle 8 is connected to the bottom outlet of the egg collection trough 7.

[0030] The mouth of the collection bottle 8 is inserted into the bottom outlet of the egg collection trough 7; this facilitates quick disassembly, replacement, and collection of insect eggs.

[0031] The inner wall of the egg collection trough 7 is attached with Velcro hooks, which can hook onto the remains of rice moths and adsorb scales, so that clean eggs fall into the collection bottle 8; the rice moth remains stuck to the inner wall of the egg collection trough 7 are cleaned regularly to prevent the outlet of the egg collection trough 7 from being blocked.

[0032] like Figure 6 As shown: Ribs 1 and 2 supporting drawers are provided on both sides of the cabinet 1.

[0033] The top panel of cabinet 1 has an observation window 1.1, which allows staff to check the number and status of adult insects emerging from the top layer of the adult insect capture drawer at any time, so as to decide when to insert the mesh plate 6 and replace the drawer, making management more timely and accurate.

[0034] like Figure 7 As shown: The adult insect trapping drawer 2 has slots 2.1 on both sides of its side walls. The mesh plate 6 is inserted into the slots 2.1 on both sides of its side walls. The slots 2.1 restrict the mesh plate 6 from moving up and down.

[0035] like Figure 4 , Figure 5 As shown: A baffle 9 with a torsion spring is hinged to the inside of the insertion interface of the mesh panel 6 on the adult insect trap drawer 2. When the mesh panel 6 is pulled out, the torsion spring pushes the baffle 9 to close the insertion interface, preventing the moths inside from escaping. After the mesh panel 6 is inserted, it pushes the baffle 9 to flip up. The width of the baffle 9 is greater than the total width of the mesh panel 6. When the mesh panel 6 pushes the baffle 9 to flip up, the bottom edge of the baffle 9 slides in contact with the top surface of the mesh panel 6's frame. Therefore, when the mesh panel 6 is pulled out, the baffle 9 will not jam the mesh panel 6.

[0036] Specific feed (such as a mixture of wheat bran, corn flour, yeast powder, etc.) is placed in the larval rearing drawer 3, and then newly hatched larvae are placed in it. The newly hatched larvae feed and grow in the feed. After the newly hatched larvae grow into adults and emerge, they fly to the mesh 5 of the adult trapping drawer 2 and observe the number of rice moths on the mesh 5 through the observation window 1.1 of the cabinet 1. After inserting the mesh plate 6 into the adult trapping drawer 2, the adult trapping drawer 2 is pulled out of the cabinet 1 as a whole, and then a new adult trapping drawer 2 without the mesh plate 6 is placed in to continue capturing rice moths. The adult trapping drawer 2 containing rice moths is placed at the bottom of the cabinet 1 to replace the adult oviposition drawer 4. The rice moths mate and lay eggs in the adult oviposition drawer 4, and the eggs fall through the mesh of the mesh plate 6 into the egg collection trough 7 and finally into the collection bottle 8.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
